TOOTH AND BASE ,FOR PHOSPHATE-LOGS.

SPECIFICATION forming part of Letters Patent No. 698,374, dated April 22, 1902.

. Application filed November 26, 1901. $erial No. 83,709. (No model.)

To all whom it may concern:

Be it known that I, ELMER E. CLINE, a citizen of the United States, and a resident of Ocala, in the county of Marion and State of Florida, have invented a new and Improved Tooth and Base for Phosphate-Logs, of which the following is a full, clear, and exactdescription.

My invention relates to a tooth of the kind used upon rotating logs for working phosphate and to a base for supporting said tooth upon said logs.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims. 1

Reference is to be had to the'accompauying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional view showing my invention as applied to a phosphate-log. Fig. 2 is an enlarged fragmentary section upon the line 2 2 of Fig. 4. Fig. 3 is a section upon the line 3 3 of Fig. 2. Fig. 4c is a fragmentary plan of the base as applied to a log, and Fig. 5 is a perspective View of the tooth..

Within a trough 1 a log 2 of the usual angular shape is revolubly mounted and is provided with an annular flange 3. Upon the log 2 the several bases 4 are secured in position by means of the bolts 5 and 6. bead is formed upon the outer surface of the base-plate, as shown at 7, forming a thick portion adjacent to the angle 8 of the log.

This is for the purpose of preventing the base plate from breaking at a point where my experience has shown me they are liable to be weak. The teeth are shown at 9, and each consists of a substantially cubical end 10, a wedge-shaped part 11, and a double-wedgeshaped part 12, all three of said parts being integral. The bottom of the tooth is provided with a recess 13 for straddling the bolt 6 and with s ern icylindrical apertures 14: for the purpose of engaging the wooden pegs 15. The base-plates 4 are each provided with a recess 16 of substantiallywedge shape and also with semicylindrical apertures 17 for engaging the wooden pegs 15, as shown more A raised particularly in Fig. 4.. The tooth is mounted by sliding the double-wedge-shaped member 12 into the recess 16, bringing the apertures l4= of the tooth opposite the apertures 17 of the base and driving the pegs 15 into the cylindricalholes formed by the oppositely-disposed semicylindrical apertures. The apertures 18 and 19, receiving the screws 5 and 6, are preferably chilled for the purpose of hardening them and increasing their durability. The extreme lower corners of the wedgeshaped member 12 are slightly rounded, as in dicated in Fig. 5, for the purpose of distributing the strain and preventing breakage of the tooth or plate. The wooden pegs 15 when driven into their respective holes slightly diverge from each other, as indicated in Fig. 3. They thus form a very effective anchor .and prevent displacement of the teeth. When, however, it is desirable to remove one or more of the teeth, the pegs are extracted without any trouble and the teeth readily removed.

The shape of the recess 16 is such that the The bases and teeth are arranged spirally I upon the log in the usual manner. W hen the log is rotated and phosphate and water are poured into one end of the trough, the action of the teeth is to agitate themixture, gradually working the phosphate up to a particular end of the log.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As an article of manufacture, a device of the kind described, comprising abase-plate provided with a recess having substantially the shape of a double wedge and also provided with semicylindrical apertures merg ing into said recess, a tooth provided with an enlarged portion having substantially the shape of a double wedge and also provided with semicylindrical apertures mating said apertures of said base-plate, and cylindrical pegs of resilient material, for detachably engaging all of said apertures.

2. As an article of manufacture, a baseplate having a recess provided with overhanging walls, said walls having oppositely-disposed semicylindrical apertures diverging from each other, a tooth provided with an enlarged portion having substantially the shape of a double wedge for engaging said recess and also provided with semicylindrical apertures diverging from each other and engaging said semicircular apertures of said walls, means for securing said base-plate to a log, and cylindrical pegs to be driven into said semicylindrical apertures.

3. As an article of manufacture, a device of the kind described, comprising a base-plate provided with an angular bend adapted to fit the surface of an angular log, and also provided with a recess, a raised bead extending across said recess adjacent to said bend and flush with the bottom of said recess so as to form a continuation of said bottom, a tooth provided with a substantially wedge-shaped portion for engaging said recess, and means for securing said tooth within said recess.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
